Intraradicular Dentinal Changes Following Fiber Postremoval: Micro-computed Tomography Analysis.

Context: Excessive dentine wear during postremoval can occur due to the adhesion between the cement and the post.

Aim: The aim is to evaluate dentine wear and microcrack occurrence following the removal of intraradicular fiberglass posts that were previously cemented with two types of resin cement.

Methods: Distal roots ( = 38) of lower molars were instrumented, filled, prepared for intraradicular postinstallation, and divided into two groups according to the cement used for the posts: RelyX ARC or RelyX U200.

Ionic concentration in periradicular medium after dissolution of endodontic file fragments: an in vitro study.

The aim of this study was to obtain ionic quantification in periradicular medium after diffusion tests of the solution used inside root canals during the electrochemical dissolution of endodontic file fragments and the NiTi-containing dissolution product via an apical foramen. Thirty single-rooted extracted human teeth had root canals prepared and were attached to Eppendorf tubes filled with sterile saline. The samples were divided into 3 groups (n = 10) according to the solution used inside the root canal during the diffusion tests: Group 1: [NaF 12 g/L + NaCl 1 g/L]; Group 2: [NaF 12 g/L + NaCl 1 g/L + NiTi 0.

Risk factors for traumatic dental injuries in the Brazilian population: A critical review.

Background/aims: Strategies for the prevention of traumatic dental injuries (TDI) should consider the risk factors involved for each population studied. The aim of this study was to perform a critical review regarding the risk factors for TDI in the Brazilian population.

Materials And Methods: A systematic literature search was performed in the MEDLINE, Scopus, Web of Science, Lilacs, and BBO databases using MeSH terms, synonyms, and keywords, with no language or date restrictions.

Profile of intrusive luxation and healing complications in deciduous and permanent teeth - a retrospective study.

Objective: This retrospective study analyse the profile of intrusion in deciduous (DT) and permanent teeth (PT), the occurrence of healing complications (HC), type of treatments and predisposing factors.

Methods: The records of patients attended from 2005 to 2011 were analysed. Records of patients who had one or more intruded DT or PT were included in the study.

Management of a Permanent Maxillary Lateral Incisor with Vital Pulp and Necrotic Dens Invaginatus Type III.

This is a case report on the management of a vital lateral incisor with a radiolucent cervical area associated with the presence of necrotic pulp due to a dens invaginatus (DI) type III. A nine-year-old boy presented to a university pediatric dental clinic with dental trauma. The examination showed poor oral hygiene, an uncomplicated fracture in the permanent maxillary left central incisor, and a fistula near the permanent maxillary right lateral incisor.

Electromagnetic interference of dental equipment with implantable cardioverter defibrillators.

Objective: Implantable cardioverter defibrillators (ICDs) are subject to electromagnetic interference (EMI). The aim of this study was to assess both the EMI of dental equipments with ICDs and related factors.

Materials And Methods: High- and low-speed handpieces, an electric toothbrush, an implant motor and two types of ultrasonic devices were tested next to an ICD with different sensitivity settings.

Ability of Three Endodontic Sealers to Fill the Root Canal System in Association with Gutta-Percha.

Introduction: The present study compared the ability of the endodontic sealers AH Plus, Pulp Canal Sealer and EndoREZ to fill the root canal system in association with gutta-percha.

Methods: Ninety mandibular premolars were accessed, prepared and divided into three groups of 30 teeth each, according to the sealer used to fill the canals: AH Plus, Pulp Canal Sealer and EndoREZ. All the teeth were filled using the continuous wave of condensation technique.

Electromagnetic interference of endodontic equipments with cardiovascular implantable electronic device.

Objectives: Assess the electromagnetic interference (EMI) of endodontic equipment with cardiovascular implantable electronic devices (CIEDs) and related factors.

Methods: The laser device, electronic apex locators (EAL), optical microscope, endodontic rotary motors, gutta-percha heat carrier (GH), gutta-percha gun and ultrasonic device were tested next to CIEDs (Medtronic and Biotronik) with varied sensitivity settings and distances. CIEDs were immersed in a saline solution to simulate the electrical resistence of the human body.

Prevalence of soft tissue injuries in pediatric patients and its relationship with the quest for treatment.

Background/aim: Soft tissue injuries (STI) are common in children and adolescents. This retrospective study evaluated the frequency of STI, gender, type of injury, and its location in pediatric patients, comparing the different age groups and how the presence of these lesions influences the pursuit for immediate care.

Material And Methods: Medical records of patients 0-15 years old who had been treated between 2005 and 2013 at the Dental Trauma Surveillance Center, School of Dentistry, Universidade Federal do Rio de Janeiro were included in this study.

Traumatic dental injury in permanent teeth of young patients attended at the federal University of Rio de Janeiro, Brazil.

Background/aim: Risk factors for dental trauma, such as gender and age, have not been studied in much detail in the past. So, this study was to determine the frequency of Traumatic dental injuries (TDI) and the association of gender and age with the different types of injuries in permanent teeth of patients treated at the Dental Trauma Surveillance Center, Federal University of Rio de Janeiro, Brazil.

Material And Methods: Data from records of 1022 patients were evaluated, and patients with TDI in permanent teeth were included and descriptively analyzed.

Epidemiologic survey of traumatic dental injuries in children seen at the Federal University of Rio de Janeiro, Brazil.

This epidemiologic survey aimed at assessing the prevalence of traumatic dental injuries in children seen at the Federal University of Rio de Janeiro, Brazil. The records of a total of 111 children (aged 0 to 6 years) seen from 2004 to 2006 in the dental trauma clinic were surveyed, comprising a total of 201 traumatized primary teeth. Data pertaining to the child and to the trauma such as age, gender, etiology, teeth involved, type of traumatic injury, time elapsed between the trauma and seeking care, and the presence and kind of clinical and radiographic sequelae in the first visit were collected from the dental records.

Postoperative pain and associated factors in adolescent patients undergoing two-visit root canal therapy.

This prospective study investigated the frequency and intensity of postoperative pain and identified associated factors in adolescents undergoing two-visit root canal therapy. Sixty-four patients aged 11 to 18 years old presenting with molars with pulp necrosis were assigned consecutively to two visits (plus an interappointment dressing using calcium-hydroxide paste). Pain intensity was recorded on a visual analogue scale (VAS) of 0-5.

There are few published reports that discuss oral burns in children. Electrical, chemical, and thermal agents are the main causative agents of these burns. Some chemicals can cause burning in the mucosa of cheeks, lips, tongue, and palate.

Assessing the proposed association between tooth agenesis and taurodontism in 975 paediatric subjects.

Background: An association between tooth agenesis and taurodontism has been suggested. The identification of subpopulations with specific associated dental anomalies (subphenotype) would allow testing of the specific hypothesis that certain genetic factors contribute to the specific subphenotype.

Aim: This work aims to assess a large cohort to verify if the association between tooth agenesis and taurodontism is present.
